Coauthored saturation spectroscopy of sodium using a pulsed tunable dye laser, resolving hyperfine structure. A delayed probe detected velocity-selective optical pumping, while time-resolved measurements followed collisional redistribution in an argon buffer gas.^[ref]

Constructed, jointly with a coauthor, a radiometer and receiving horn for absolute thermal-radiation measurements at $3\mathrm{cm}$. The associated cosmic microwave background paper explained the wavelength choice as a compromise between atmospheric absorption and longer-wavelength foregrounds; results from this instrument were still pending.^[ref]

Coauthored the hot-universe interpretation of the cosmic microwave background. The analysis explained how cosmological redshift could cool primordial black-body radiation while preserving its thermal spectrum, and considered whether the reported microwave excess was this relic radiation.^[ref]

Coauthored the Gargamelle observation of neutrino interactions producing hadrons without a final-state muon or electron. Comparing these events with charged-lepton-producing interactions provided evidence for the weak neutral current.^[ref]

A researcher whose joint review with Robert Otto Pohl analyzed thermal boundary resistance. A temperature difference can persist across an interface carrying heat because energy carriers do not transmit perfectly between materials. Comparing acoustic-mismatch and diffuse-mismatch models relates that macroscopic resistance to how phonons transmit or scatter at the boundary.^[ref]

Coauthored the discovery of the J/psi meson in electron-positron annihilation. Scanning the collision energy revealed a sharp enhancement in production of hadrons and electron-Positron pairs near $3.105\mathrm{GeV}$, with a reported full-width upper limit of $1.3\mathrm{MeV}$.^[ref]

Coauthored the observation of the J/psi meson through a narrow peak near $3.1\mathrm{GeV}$ in the invariant mass of electron-Positron pairs. The experiment used a precise pair spectrometer to analyze products of protons striking a beryllium target.^[ref]

Coauthored the discovery report of pulsars, using an $81.5\mathrm{MHz}$ radio telescope for scintillation surveys. Repeated signals at a fixed sky position helped distinguish the source from terrestrial interference.^[ref]

A researcher whose neutron studies connected lattice vibrations with structural changes in uranium. His team reported a low-temperature charge density wave and strong precursor changes in the phonon spectrum. The experiment shows why studying atomic motion can reveal an approaching instability before a new ordered structure is fully established.^[ref]

A neutron-scattering researcher whose joint work developed polarization analysis. Distinguishing the spin states of neutrons before and after scattering adds information beyond the total scattered intensity, helping separate different contributions to a material’s response. His work connects the quantum properties of the probe with practical measurements of condensed matter.^[ref]

Coauthored the observation of the Omega baryon in a hydrogen bubble chamber exposed to a kaon beam. Reconstructing the decay chain and its kinematics identified a negatively charged particle with strangeness $-3$ and measured mass near $1686\mathrm{MeV}/c^2$.^[ref]

A physicist whose joint measurements with R. E. Glover III used infrared and microwave transmission to probe superconductivity. The dissipative and reactive parts of electrical conductivity changed differently with frequency. Comparing tin and lead films exposed a common scaled response and an excitation threshold, providing a quantitative way to investigate the superconducting energy gap.^[ref]
